Cell wall and Chloroplast which are found in Plant cell but not in animal cell.
Answer:
The starting number is 78.
Explanation:
(x / 3) / 2 = 13
divide a number by 3 (x / 3)
divide in half (x / 3) / 2
You get 13 (x / 3) / 2 = 13
Reverse the problem.
13 * 2 = 26
26 * 3 = 78
x = 78
Plug in the number.
(78 / 3) / 2 = 13
78 / 3 = 26
26 / 2 = 13
